A further update and sadly not the best!
Having found and paid for a brand new body control module advertised in Japan which exactly matches my car, a week on and they`ve just emailed to say it`s no longer available and effectively `there are no more`, Nissan stopped production. So my question is, before I buy a similar bcm and hope it might work with recoding from Nissan, can these things be repaired? I have seen an old post on the forum from July 2011 which says `Husky` repairs bcm`s.
The auto electrician I`m using reckons the water damage is too great to repair, but I`d like another opinion if anyone can suggest someone or knows of Husky?
Alternatively a replacement ecu, bcm and key all paired for a 2002 JDM automatic, ........... hens teeth?
